Giant globules of molten rock are defying the laws of physics by floating up out of an ancient glacier in this science fiction mystery!Geology instructor Alex Cave receives an urgent message about an unusual event in Iceland, creating a huge spiral tunnel down into the dormant volcano. Alex and his friend, Okawna, descend deep into the mountain, seeking answers to the strange phenomenon, and are reluctantly joined by Janice Sloan, a ruthless woman dealing in stolen technology, and John Essex, a billionaire scientist fanatical about conquering outer space and mining the moon. What they discover at the bottom is an alien artifact more powerful than a nuclear weapon.
Sloan steals the device and activates it, but cannot turn it off. It begins dragging satellites from space and threatens to bring down the International Space Station. When it changes the orbit of the moon, the extreme tidal effect starts destroying the shorelines on a global scale.
And if that isn't enough, a gold asteroid is on a collision course with Earth, and will impact in six days. Alex's only chance of changing its trajectory is with the alien device, and he's running out of time to locate it.
